If am trying to roughly calculate the outcome of an attack, would it be correct for me to assume that if a unit that starts the turn with 80 AP it should have its attack factors reduced by 20%?

And the same for defense -- if I am trying to estimate how strong my defenders will be for the impending attack by my opponent, are my units that have 80 AP going to be 20% less effective than my units that have 100AP?

If this not correct would someone explain to me how to account for the AP differences when attacking and defending?

If you had two identical units, same everything except one has 100AP and the other has 70AP, I am not a math whiz, but I would think that the one with 100AP (getting ten rounds of combat as opposed to the the one that gets 7 rounds) would mathmatical have it better. I just do not know if it is 30% better or something in between. Of maybe as you two say, it makes no difference.

Because if AP does matter, then moving AND having combat really hurts you because you; (a) lose Readiness and, (b) rounds of combat (AP).

Hmmm. Well said. I am not a math expert, but that still sounds like the APs are directly correlated to the combat outcome. More specifically, would a unit with 70 AP have 30% less chance of being successful in attacking than an identical unit with 100AP. I cannot do the math, but I feel like I am on to something.., but then again..., damn-it, I wish I was smart.

I'm not sure if the AP's of the defender matter. They seem to return fire until you run out of AP's as the attacker or until they retreat/break.

Even though you're technically correct that more AP's statistically increase the chance to win or inflict more casualties, the effect does seem to drop off after a certain number of rounds. Based on my limited experience, most if not all of the defending units generally show some form of retreat result at about round 7 or 8.

I think that the defenders AP's don't matter, only the attacker's one. "These individuals then battle it out for several rounds, each round costing 10 AP. The moment an attacking unit is out of AP, it ceases combat."

So if a unit has 10 AP's left, it can conduct at least one round of combat?

To attack, you must have more than 10 APs left otherwise you could enter a hex after having won the battle, a hex that you could not have enter if it had been empty ! You see "red arrows" telling you if you will be abble to conduct another attack if you move near an adjacent ennemy unit.
